I was thinking about this the other day because I feel like I'm in the minority, but I see a few others who have had a similar experience. I certainly agree with others that the answer to this can widely vary.

A Lightning or a LWB is way too vertical for me. For whatever reason I even find the recurve seat on Bacchettas to be far less comfortable than the euromesh. Personally, I've found my Bacchetta with the euromesh seat and covered foam pad to be incredibly comfortable.

They changed their seat foam to a thinner one, which exposed the rear to the upward bend in the seat frame, they made a jig to bend it back if you sent your seat in, it's been discussed here for quite awhile and at length.

My Vivo has the original thick foam so my 230lbs is well supported. I wish I could buy the original foam for my other Rans seats.

Lightning R-84, comfortable mesh seat that allows air circulation to back and bottom sides (no extra seat pad on the seat). Somewhat upright seating position which is comfortable. Front and rear suspension to soak up road undulations and potholes. If I was doing a coast to coast supported leasure trip, I'd probably take it.

The one I found fit me best was the barcroft ti lowracer I owned breifly. There were issues with the frame, but I won't get into that.
Second maybe first is my old junk shop Tour Easy.
Very different bikes. In rider postion.
I also love high racer bikes, but lack flexible enough hip joints to put a foot down at stops. If I was compatible with that type I would ride nothing else.

Comfort for me, is a function of the seat and the bottom bracket location. My favorite bikes for comfort have been those with RANS soft seats and high bottom brackets. These include, a Barcroft Virginia with a standard RANS seat, VRex with the same, several Xstreams with sling mesh seats, and a RANS enduro with a sling mesh.

I have owned some of each (this is actually a gross understatement). I cannot get comfortable, no matter what the seat on a tour easy. I also ride a Ranger which is OK, but not as comfortable as the above (for me). I think the Ranger bottom bracket may be just slightly higher than the Tour Easy.
